You are seeing this page because development mode is enabled. Development mode, or devMode, enables extra debugging behaviors and reports to assist developers. To disable this mode, set:

struts.devMode=false
in your WEB-INF/classes/struts.properties file.

 错误是,java.lang.NoClassDefFoundError: Could not initialize class HibernatePage.HibernateUtil
 看路径下有没有这个java文件。如果有java文件,看看classes有没有生成class。如果没有生成,那刷新一下环境或者重启一下myeclipse试试

这个有好几种情况啊,类未写全吧?还有就是路径的问题,或者是包的问题。我最近也在烦路径的问题。
你打开DBUg 一步一步调试看看,哪一步出现了问题。希望对你有帮助。

要不要对Action.RegisterAction.execute();方法,以及DAO中的saveUser()和addUser()方法检查一遍并重启tomcat试试看?

Could not initialize class HibernatePage.HibernateUtil 类HibernateUtil没有初始化成功造成没法生成HibernateUtil的class文件,对于UserDaoHibernate.java:使用时又依赖HibernateUtil类,所以就造成了没有NoClassDefFoundError问题,看看编译器版本及HibernateUtil依赖类没有加载的原因

HibernatePage.UserDaoHibernate.saveUser(UserDaoHibernate.java:27)
Beans.userDbase.addUser(userDbase.java:10)
这两句有没有写错
